She reported several similar episodes over the past years. Physical examination was unremarkable. A temporal bone CT scan revealed dehiscence between the bony carotid canal and the cochlea resulting in the diagnosis of carotid-cochlear dehiscence (CCD). CCD is an extremely rare condition involving the thinning of the bony canal separating the internal carotid artery from the cochlea. CCD is best diagnosed with temporal bone CT scan. Treatment options include observation as well as chemical or surgical labyrenthectomy. Despite similar clinical and diagnostic characteristics of reported CCD cases, general trends and consensus on treatment options cannot be ascertained due to the extreme rarity of this condition. Regardless of these limitations, CCD is a critical diagnosis as it mimics other inner ear conditions and poses a potential, significant surgical risk for the otolaryngologist.<\/jats:p>","DOI":"10.1136\/bcr-2019-229773","type":"journal-article","created":{"date-parts":[[2019,7,18]],"date-time":"2019-07-18T06:55:14Z","timestamp":1563432914000},"page":"e229773","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Carotid-cochlear dehiscence: a dangerous mimicker of inner ear pathologies"],"prefix":"10.1136","volume":"12","author":[{"given":"Sina","family":"Koochakzadeh","sequence":"first","affiliation":[{"name":"Medical University of South Carolina, Charleston, South Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James R","family":"Dornhoffer","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina, Charleston, South Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua D","family":"Horton","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina, Charleston, South Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ted A","family":"Meyer","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina, Charleston, South Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,7,17]]},"reference":[{"key":"2025082800474206000_12.7.e229773.1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.5541040515"},{"key":"2025082800474206000_12.7.e229773.2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.130.12.1427"},{"key":"2025082800474206000_12.7.e229773.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2005.04.006"},{"key":"2025082800474206000_12.7.e229773.4","doi-asserted-by":"crossref","first-page":"909","DOI":"10.1097\/MAO.0b013e318225573f","article-title":"Simultaneous true stapes fixation and bilateral bony dehiscence between the internal carotid artery and the apex of the cochlea: the ultimate pitfall","volume":"32","author":"Neyt","year":"2011","journal-title":"Otol Neurotol"},{"key":"2025082800474206000_12.7.e229773.5","doi-asserted-by":"publisher","DOI":"10.1002\/lary.22391"},{"key":"2025082800474206000_12.7.e229773.6","doi-asserted-by":"crossref","first-page":"1126","DOI":"10.3109\/00016489.2012.684400","article-title":"Aberrant internal carotid artery causing objective pulsatile tinnitus and conductive hearing loss","volume":"132","author":"Song","year":"2012","journal-title":"Acta Otolaryngol"},{"key":"2025082800474206000_12.7.e229773.7","first-page":"1486","article-title":"The cochlear-carotid interval: anatomic variation and potential clinical implications","volume":"27","author":"Young","year":"2006","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025082800474206000_12.7.e229773.8","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A4922"},{"key":"2025082800474206000_12.7.e229773.9","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1007\/s12070-013-0643-9","article-title":"The importance of carotid-cochlear interval in the etiology of hearing loss","volume":"65","author":"Cetin","year":"2013","journal-title":"Indian J Otolaryngol Head Neck Surg"},{"key":"2025082800474206000_12.7.e229773.10","doi-asserted-by":"publisher","DOI":"10.1177\/197140091102400315"},{"key":"2025082800474206000_12.7.e229773.11","doi-asserted-by":"crossref","first-page":"551","DOI":"10.1007\/s00276-015-1607-4","article-title":"The impact of the cochlear-carotid interval on tinnitus perception","volume":"38","author":"Gunbey","year":"2016","journal-title":"Surg Radiol Anat"},{"key":"2025082800474206000_12.7.e229773.12","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1159\/000369622","article-title":"Contemporary neuroradiographic assessment of the cochleo-carotid partition","volume":"78","author":"Shoman","year":"2016","journal-title":"ORL J Otorhinolaryngol Relat Spec"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-229773","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T07:47:50Z","timestamp":1756367270000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-229773"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7]]},"references-count":12,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2019,7,17]]},"published-print":{"date-parts":[[2019,7]]}},"alternative-id":["10.1136\/bcr-2019-229773"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-229773","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7]]}}}
